SK8 GE3K

ok well i downloaded this and made an account and tried to log into the game itself but when i did it didnt work it said invalid username or password so i tried it for an hour.... after that i tried making a new account and still the problem kept coming up... i made sure it is registered and everything is right... but the game stil wont sign me in
